FORD 2015 Fusion - Manual (Page 208)

If it is, a red warning light illuminates and
an audible warning chime sounds.
The brake support system assists the driver
in reducing the collision speed by charging
the brakes. If the risk of collision further
increases after the warning light
illuminates, the brake support prepares
the brake system for rapid braking. This
may be apparent to the driver. The system
does not automatically activate the brakes
but, if the brake pedal is pressed, full force
braking is applied even if the brake pedal
is lightly pressed.
Using the Collision Warning System
WARNING
The collision warning system’s brake
support can only help reduce the
speed at which a collision occurs if
the driver applies the vehicle’s brakes. The
brake pedal must be pressed just like any
typical braking situation.
The warning system sensitivity can be
adjusted to one of three possible settings
by using the information display control.
See (page 93).
Note: If collision warnings are perceived as
being too frequent or disturbing then the
warning sensitivity can be reduced, though
the manufacturer recommends using the
highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings. See (page 93).
Blocked Sensors
E145632
If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor have been
obstructed. The sensors are located behind
a fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot be
detected and the collision warning system
does not function. The following table lists
possible causes and actions for this
message being displayed.
